A recent crackdown by the Federal Motor Carrier Safety Administration (FMCSA) on English-language proficiency has led to more than 1,200 truck drivers being removed from active service across the U.S. since June 25, 2025. The enforcement follows a revived federal directive that reinstates strict adherence to English-language standards for commercial motor vehicle (CMV) operators.
Background on the Policy Shift
The FMCSA’s renewed enforcement efforts stem from a directive issued in late May by U.S. Transportation Secretary Sean Duffy. The directive reversed a 2016 policy that had deprioritized English-language proficiency as a roadside enforcement concern. As of June 25, state inspectors began issuing out-of-service (OOS) violations to drivers who could not communicate effectively in English during roadside inspections.
According to FMCSA’s Analysis & Information Online database, 1,212 such violations have been recorded. These involve drivers who could not speak or read English sufficiently to:
- Respond to official questions from inspectors
- Understand highway signs or signals
- Communicate with the general public
- Complete entries in official records or reports
While Duffy’s public statement cited around 1,500 removals, the official database reports 1,212 verified OOS actions. Discrepancies likely stem from delays in data reporting by state agencies.
Enforcement Guidelines and Process
Under FMCSA guidance, all roadside inspections must begin in English. If inspectors believe the driver doesn’t comprehend initial instructions, a language proficiency interview is conducted. If the driver cannot meet proficiency requirements, specific violations are cited, and the driver is taken out of service immediately.
Inspectors must document the reasons for each violation, and drivers are not allowed to use interpreters, translation apps, or written aids during assessments.
Who Was Affected?
Interestingly, 99% of drivers cited for language violations were employed by U.S.-domiciled carriers. Carriers from Canada and Mexico accounted for less than 1% of the cases. This suggests that the issue is not isolated to foreign operators but instead reflects broader domestic language training gaps within the industry.
The FMCSA divides the U.S. into four inspection regions, and violation counts per region include:
- Western Region: 412 violations (highest)
- Southern Region: 364 violations
- Midwestern Region: 273 violations
- Eastern Region: 163 violations
The Western region also led in violations related to inability to understand English-language traffic signs and signals.
Industry Implications
The trucking industry has largely backed the renewed enforcement. Advocates argue that communication skills are essential for safety, especially when navigating complex traffic conditions or interacting with law enforcement.
However, this sudden increase in enforcement could pose challenges for carriers with diverse, multilingual fleets. The policy shift may require companies to enhance driver training programs and ensure all drivers can pass on-the-spot proficiency evaluations.
The FMCSA’s monthly data updates are expected to track the continued impact of this enforcement effort. Carriers are encouraged to monitor driver compliance closely and prepare for further regulatory scrutiny in the months ahead.
